Inference Kernel Ncu Profile

Q: What is a Claude Code skill and how does the Inference Kernel Ncu Profile skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Inference Kernel Ncu Profile is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

Capture per-kernel CUDA hardware-counter data (occupancy, achieved warps active, regs/thread, smem/block, DRAM throughput, arithmetic intensity, branch divergence %, warp-stall reason %) from a live vLLM inference pod via an `ncu` debug sidecar (no production image rebuild). Outputs `.ncu-rep` + per-kernel CSV. Scoped via `--kernel-name` to avoid the 10-100x kernel-replay slowdown that an unscoped ncu attach would impose on serving. Pairs with `inference-kernel-profile` (nsys: absolute kernel duration + cuda-graph timeline) and `zymtrace-anchored-query` (sample- share + kernel-name resolution). Triggers on "ncu", "nsight compute", "kernel internals", "occupancy", "register pressure", "shared memory", "DRAM bandwidth", "roofline", "arithmetic intensity", "warp stalls", "branch divergence", or any combination of "ncu / nsight-compute / occupancy / regs / smem / dram / roofline" with "vllm / kimi / glm / deepseek / inference".
